I am not getting an error when visiting the cpanel login link, however that link may be blocked on the network you are on due to port security settings. You can try to get to the cpanel login via http://cpanel.mrtanyc.com this will allow you to go around the port blocking by using the standard internet port 80.

As to the login at mrtanyc.com/admin.php, I have no way of checking the credentials to ensure they are correct without access to the database itself. For that, I would need the current cpanel password. If you would like to provide that information for further testing, you can send it to docs@inmotionhosting.com Be sure to validate your account with either the last 4 digits of the credit card on file, or the current Account Management Panel (AMP) password.

As we do not actively monitor that address, be sure to leave a comment below so we know the information was sent.
